I've been meaning to ask this and don't remember the places where I have seen it. But now a merchant has spent hours trying to figure out why all his option choices are not showing when they showed in Gold. He has two options and option 1 is sizes and option 2 is distributors. There are a some sizes that are not available from all distributors, but on the Gold site they showed up in the dropdown anyway on the store site. You could see all the sizes in the dropdown to start with and when you changed the distributor in another dropdown, only the sizes from that distributor would show, which is correct in AC9. But when you first load the AC9 page, not all the sizes show like the do in Gold. I found a setting in the productmodel for ShowAllOptions and changed that to true. But that choice to ShowAllOptions isn't shown in the admin when you click on the parameters icon for the BuyProductDialog.
Why are some "parameters" not changeable except in controllers or models? You can't set them via the admin or in the view, in any way I could find.
Thanks
